This was encountered during real-world use, not just theoretical. Tested with the existing fscrypt xfstests, and with a new xfstest I wrote to reproduce this bug. This fix does expose an existing bug with '-o lazytime' that Ted is working on fixing, but this fscrypt fix is more critical and is needed anyway regardless of the lazytime fix. ---------------------------------------------------------------- Eric Biggers (1): fscrypt: don't evict dirty inodes after removing key fs/crypto/keysetup.c | 9 +++++++++ 1 file changed, 9 insertions(+)
